Nice!!!!

Looks great Nate. I think you should look into nickel plating the copper parts though..
 
Any thoughts on those specs John?

Dang that plexi's awesome!
 
P.S. Nate if you ever want someone to help design more blocks (and ln2/dice pots too), hit me up with a PM or something. I dunno if i could help with the coding, but if i ever figure out a way to do that too, i would be able to be even more helpful.

now that is some eye candy. great job nate.

you cant just sit there and let them charge it or else it wont get charged right. and it'sd not cheap either!.. you really only need someone to buy it for you...then charge away. they will try to charge it according to their specs and not yours. it will then be under charged for the most part. not sure if they will let you just sit there with a motherboard though...lol..mine did the first few times, till i learned on my own.

 
Interesting. Gonna have to read some more about that then. Any idea on compressor sizes/temps/watts?

Keep working on them Halo...Parents that is.  They may not see any value in the actual end product, but sell them on the fact that it helps you to develop real world problem solving skills using mathematics, physics, geometry, engineering....the list goes on;)

Actually my dad is pretty supportive of me learning to build phase units surprisingly enough. I would need someone else to charge them as I'm not HVAC certified though. Ideally I'd build a little SS for 24/7, and either a dual or triple stage for benching.

Hell, if I made a decent SS I could sell a few.

 
Start with a single stage, captube system.
 
Best bet is to pick up a complete 1/3 HP Copeland condensing unit designed for r404 or r410a and use that as your system base.
 
11'  of .032 I.D. captube should be a good starting point for tuning to a 200 watt load running an R290 .
you can just use Standard propane from a Bernz-o-Matic torch cylinder , just run it through a filter drier when charging to remove any possible moisture .
 
Youll need...
A turbo torch, 5% silver brazing rods, flux, a set if manifold gauges and hoses, a Multimeter with temperature measurement ability, tubing cutter, a couple schrader valves, captube, Filter drier, cpu evaporator, and an old refrigeration compressor to use as a vacuum pump.
 
That should about cover the basics....
 

i would talk to drewmister first...
and the chilly1 is old school and out of date. you want a kyal evap(i thinks thats the name)
and you want something in the 3/4 hp range. we are using rotarys, but they are noisy. the rec are much quieter and can be restarted quicker.

It's kayl evaps.

Also you probably knew this Halo, but rotaries are cheaper than reciprocating. But like John said, rotaries are alot more noisy. You just have to prioritize, $ or noise.

 
Here's the two I'm looking at for a SS:

For my dream of building a cascade I'd use 2 or 3 of either of those, or possibly 2 or 3 of the 3/4HP models. I haven't yet found a place to get condensors though, or the heat exchangers needed for a cascade. I know RunMC has them on his site, but not sure how good that one is.

i would not go lower than 1/2hp and that is pushing it. 3/4 is a nice spot to hold temps on even a 980x (to a degree)

Taking a guess here: http://www.supremecondensers.com/index.php
 
Am I anywhere close to the right kind of condenser? If so could I use Honda/Toyota?

I assume I'd just PM him on XS?

Ah nice. Gonna have to register there then. Think it's a good idea to do a SS or two before trying a cascade?

Sooner or later, I'll have to go colder.

This phase change stuff sounds really good. The research necessary and time consumed is killing me though. Does anyone sell a good kit or offer a good parts list to get me going?

My time costs more than money right now.

 
Unless you want to invest in the tools to build then I would talk to RunMC or Sdumper.

I'll look into it.

@Nate: Your block building is getting much complex. Like said, it may be worth your while to look into the cost of having someone nickle plate your blocks.

The CPU block industry is probably much harder to get into, but if you were to attempt it, you may want to look into the cost of getting EDM notches put in copper for impingement cooling.

IIf you were to tackle the CPU block industry, you would probably want to add flare to your blocks to set them apart. I am sure it is technically possible to add tri-color LEDs to a block which would change color based on CPU fan speed setting when plugged into a CPU fan header.

How do you know if a phase hange unit is adequate? Just look for a 3/4 HP unit or greater and hope that the rest is built well?

I would probably start with my old X58 and 965 with one of the many cheap video cards I have laying around.

 
Really you want one that is tuned for a specific load. Ie I want my SS to be -40C @ 300W load.
